90° on Nov. 16, 2025, the hottest reading for this week of the year since 1894. Next is 89° in 1911.
Davis’s center stands about 1,170 ft above sea level. Within three miles the land runs from 800 ft to 1,310 ft, a difference of 510 ft: hilly country.
Under the town center the state geologic map shows Butterfly Dolomite + Signal Mountain Limestone + Royer Dolomite and Fort Sill Limestone (limestone, dolostone), from the Cambrian, 487 to 497 million years old.
The section below crosses 11 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 28×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Limestone, dolostone. Age: Cambrian, 487 to 497 million years old. About 7 mi of the line.
Shale, sandstone, conglomerate. Age: Permian, 252 to 299 million years old. About 3 mi of the line.
Sandstone, limestone, dolostone. Age: Cambrian, 487 to 497 million years old. About 3 mi of the line.
Black-shale. Age: Late Devonian, 359 to 384 million years old. About 3 mi of the line.
Limestone, conglomerate, dolostone. Age: Early Ordovician, 471 to 487 million years old. About 3 mi of the line.
Hypabyssal-rhyolite. Age: Middle Cambrian, 497 to 521 million years old. About 2 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale. 5 smaller units along the line are not listed.

A raindrop that lands in Davis reaches the Gulf of America by way of Honey Creek, the Washita, the Red River, the Atchafalaya and the Lower Atchafalaya: about 920 river miles.
680 miles of the trip are on the Red River.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Davis; river miles along the main stem, rounded.
Davis has a humid subtropical climate. Summer afternoons average 95° in July; winter nights fall to about 26° in January. About 37 inches of rain fall in a normal year, with about 2 inches of snow.
On November 14 Davis normally reaches 65° and falls to 38°. The record high is 83°, in 1973; the record low 12°, in 2018. The most rain on this date, 1.70 in, fell in 1994.
